Multiple API V3 Endpoints not working correctly?

[KW1-greysky]

Hey there!

i am currently testing the API V3 within a custom wordpress plugin for our company. We currently use a Free Plan to develop and we use your provided PHP Wrapper - which works perfectly fine for (most of) the API endpoints. But i have discovered some strange behaviour within some of the API endpoints. I am now wondering if i did something wrong or is the API messed up?

Used Software:

• PHP: 8.2
• WP: 6.6.2
• Mailjet PHP Wrapper: dev-master 04c0a3c
• Mailjet API v3
• Mailjet Sent API v3.1

API Connection:

$this->apiVersion = "v3";

$this->mj = new \Mailjet\Client( 
    $this->apiKey, 
    $this->apiSecret, 
    true, 
    ['version' => $this->apiVersion]
);

API Endpoint https://api.mailjet.com/v3/REST/campaign:

Request (it doesnt even work without the filters):

public function get_campaigns() {
        // set some filters for the request
        $filters = [
            "Limit" => 1000
        ];

        $response = $this->mj->get(Resources::$Campaign, ["filters" => $filters]);

        if ($response->success()) {
            return $response->getData();
        } else {
            return [
                'error' => true,
                'status' => $response->getStatus(),
                'message' => $response->getReasonPhrase()
            ];
        }
    }

Response expected:
array(1){ "Count": 1, "Data": [ { "IsDeleted": false, "IsStarred": false, "CampaignType": 2, "ClickTracked": 1, "CreatedAt": "2018-01-01T00:00:00", "CustomValue": "CustomTag", "FirstMessageID": 1234567890987654400, "FromEmail": "pilot@mailjet.com", "FromID": 123456, "FromName": "Your Mailjet Pilot", "HasHtmlCount": 1, "HasTxtCount": 1, "ID": 987654321234568000, "ListID": 567890, "NewsLetterID": 3456789, "OpenTracked": 1, "SegmentationID": 123, "SendEndAt": "2018-01-01T00:00:00", "SendStartAt": "2018-01-01T00:00:00", "SpamassScore": "0", "Status": 0, "Subject": "Your email flight plan!", "UnsubscribeTrackedCount": 0, "WorkflowID": 1234 } ], "Total": 1 }

Response actually:
array(0) { }

Just one of many API Endpoints that doesnt work (for me). Another API Endpoint is https://api.mailjet.com/v3/REST/campaigndraft. I can get sent campaings via the Campaigndraft Endpoint by setting the Status filter. Then i get all sent campaigns - which are obiously not in draft anymore - over the Campaigndraft Endpoint. This would be fine with me if there wasnt the problem, that this list of campaigns contains the WRONG campaign ids. I expect the campaign ID to be "6509134" but i get "255950". This is some strange behaviour that is going on there.

Here is also a (not at all) complete list of endpoints that dont work at all or return (partially) wrong data:

• https://api.mailjet.com/v3/REST/campaign (doesnt work at all)
• https://api.mailjet.com/v3/REST/campaigndraft (partially wrong data)
• https://api.mailjet.com/v3/REST/campaignoverview (not complete data, just 3 of at least 15 sent campaigns)
• https://api.mailjet.com/v3/REST/geostatistics (doesnt work at all)
• https://api.mailjet.com/v3/REST/statistics/recipient-esp (doesnt work at all)
• https://api.mailjet.com/v3/REST/useragentstatistics (doesnt work at all)

If there is still important information missing please tell me and i will try to provide the missing infos.

Cheers!
